Both are using the same type of disk Western Digital Black 1 TB and have 1333 MHz memories. I tried Ubuntu 11.04 / x86 on machine #1 using an external e-SATA Seagate disk some time ago. I do not have the exact figures, but It was within minutes of machine #2, so I think it is safe to assume that the extra time is there due to the lack of JIT compiling. End of this week, I hope to try on a 4.4 GHz (overclocked) Core-i7 2600k/Ubuntu 11.10/x64. Still only 1333 MHz memory unfortunately. -- Best Regards Ulf Samuelsson
